3. Breast Anatomy

4. Breast Anatomy Breast Made up of milk-producing glands Supported and attached to the chest wall by ligaments Rests on pectoralis major muscle Three major hormones affect the breast Estrogen, progesterone, and prolactin The breast is made-up of milk-producing glands, lobules, that are surrounded by a layer of fat. The breast contains no muscle tissue. The breasts are supported and attached to the chest wall by ligaments. The breast tissue rests on the muscle of the chest, the pectoralis major. Hormones that cause changes in the breast during the menstrual cycle are estrogen, progesterone, and prolactin. The hormones also cause breast tissue to develop, enlarge, and produce milk.The breast is made-up of milk-producing glands, lobules, that are surrounded by a layer of fat.

5. Breast Anatomy Breast contains 15-20 lobes Fat covers the lobes and shapes the breast Lobules fill each lobe Sacs at the end of lobules produce milk Ducts deliver milk to the nipple Each breast contains 15 to 20 lobes. The lobes are covered and supported by connective tissue or fat. The fat gives the breast its size and shape. Each lobe contains lobules. At the end of the lobules are the sacs that produce milk. The milk is delivered to the nipple by ducts that convey it from the lobules. The breast tissue, which includes the lobes and connective tissue (fat), is covered by skin. The nipple is located on the skin of the breast. It’s function is expression of milk produced by the lobules. The pigmented area that surrounds the nipple is the areola. Each breast contains 15 to 20 lobes. The lobes are covered and supported by connective tissue or fat. The fat gives the breast its size and shape. Each lobe contains lobules.

6. Breast Clock and Quadrants The diagram on this slide shows the right and left breasts as if the physician was looking at the patient. Each breast is divided into horizontal halves, upper and lower, and vertical halves, inner and outer. If the primary site is described as upper, lower, inner, or outer, the ICD-O-3 primary site code is C50.8, overlapping lesion of breast, because a more specific subsite cannot be determined with that description alone. The breast halves are divided into quarters or quadrants. The ICD-O-3 code for upper-inner quadrant is C50.2, lower-inner quadrant is C50.3, upper-outer quadrant is C50.4, and lower-outer quadrant is C50.5. The ICD-O-3 code for nipple and areola is C50.0. If the primary site is the central portion of the breast, subareolar, or beneath the areola use primary site code C50.1. Physicians sometimes describe the location of a breast tumor using clock positions. Again, the physician is looking at the patient and assigns the clock times from that view. So, the upper inner quadrant of the right breast is between 12 and 3 o’clock; the lower inner quadrant is between 3 and 6 o’clock; the lower outer quadrant is between 6 and 9 o’clock; and the upper outer quadrant is between 9 and 12 o’clock. When looking at the left breast, the upper outer quadrant is between 12 and 3 o’clock; the lower outer quadrant is between 3 and 6 o’clock; the lower inner quadrant is between 6 and 9 o’clock; and the upper inner quadrant is between 9 and 12 o’clock. The breast clock diagram on this slide is found on the SEER Training Website. There is also a breast clock diagram in the SEER Program Coding and Staging Manual 2004, Appendix C, page C-470. That diagram is included in your manual and located after the breast slides.The diagram on this slide shows the right and left breasts as if the physician was looking at the patient.

7. Breast Quadrants Example 1: Malignant tumor, 3 o’clock, right breast Answer: C50.8 Overlapping lesion of breast Example 2: Malignant tumor, 7 o’clock, left breast Answer: C50.3 Lower-inner quadrant The following are examples for assigning breast subsite code. The first example is a malignant breast tumor at the 3 o’clock position on the right breast. If you look at the breast clock diagram on the previous slide, you will see that 3 o’clock on the right breast is at the midline of the breast. Tumors on the midline are assigned subsite C50.8, overlapping lesion of the breast. 3 o’clock overlaps the upper and lower quadrants. Example 2 is a malignant tumor of the left breast located at the 7 o’clock position. Again, look at the breast clock diagram. 7 o’clock on the left breast is the lower-inner quadrant and the site code is C50.3.The following are examples for assigning breast subsite code. The first example is a malignant breast tumor at the 3 o’clock position on the right breast. If you look at the breast clock diagram on the previous slide, you will see that 3 o’clock on the right breast is at the midline of the breast. Tumors on the midline are assigned subsite C50.8, overlapping lesion of the breast. 3 o’clock overlaps the upper and lower quadrants. Example 2 is a malignant tumor of the left breast located at the 7 o’clock position. Again, look at the breast clock diagram. 7 o’clock on the left breast is the lower-inner quadrant and the site code is C50.3.

8. Regional Lymph Nodes for Breast Axillary lymph nodes Located in the underarm to the collarbone Include interpectoral or Rotter nodes Internal mammary (parasternal) lymph nodes Tucked under the sternum The next two slides describe regional lymph nodes for the breast. Lymph drainage from the breast begins with the axillary lymph nodes, which are located from the underarm to the collarbone. The interpectoral or Rotter nodes are classified as axillary lymph nodes. The axillary lymph nodes are sometimes described as level I, II, or III. The lowest level nodes are closest to the breast, and distance from the breast increases as the level number increases. The internal mammary lymph nodes are located under the sternum. They may also be called parasternal lymph nodes. The prefix “para” indicates that they are located around the sternum. The internal mammary lymph nodes are rarely excised in current treatment protocols.The next two slides describe regional lymph nodes for the breast.

9. Regional Lymph Nodes for Breast Infraclavicular (subclavicular) lymph nodes In the deltopectoral groove Supraclavicular lymph nodes Above the collarbone The infraclavicular or subclavicular lymph nodes are found in the deltopectoral groove. That is an area between the clavicle and the chest where the deltoid and pectoral muscles meet. The supraclavicular lymph nodes are located above the collarbone and are the regional lymph nodes located farthest from the breast. The infraclavicular or subclavicular lymph nodes are found in the deltopectoral groove. That is an area between the clavicle and the chest where the deltoid and pectoral muscles meet. The supraclavicular lymph nodes are located above the collarbone and are the regional lymph nodes located farthest from the breast.

10. Regional Lymph Nodes for Breast Points B, C, and D on this diagram are axillary lymph nodes. The level I nodes at point B are closest to the breast; the level II nodes at point C are further from the breast near the upper arm; and the level III nodes at point D are the axillary nodes furthest from the breast approaching the collarbone. Point E is the supraclavicular nodes, which are above the collarbone. Point F is the internal mammary nodes located near the sternum or breast bone.Points B, C, and D on this diagram are axillary lymph nodes.

12. Caution!! Pre-2007 Multiple Primary and Histology Rules used in the following slides are based on 2006 rules.

13. Breast Tumor Histology Majority of breast cancers are infiltrating duct carcinoma Other carcinoma Lobular, tubular, medullary, papillary, and mucinous Prognosis is worse for infiltrating duct and lobular carcinomas than for others The majority of breast cancers are infiltrating duct carcinoma. The next most common histology is lobular carcinoma. Other cancers seen less frequently include tubular, medullary, papillary, and mucinous carcinoma. The prognosis for infiltrating duct and lobular is similar, but the prognosis is better for medullary, papillary, and mucinous carcinoma of the breast according to the American Cancer Society’s Clinical Oncology (2001).The majority of breast cancers are infiltrating duct carcinoma.

14. Histology Coding Rules: Breast Rules are a hierarchy Use rules in priority order with rule 1 having the highest priority Use the first rule that applies Rules from SEER Program Coding and Staging Manual (PCSM) 2004, pages 86-87 Additional coding information for breast in Appendix C, pages C-471 and C-472 The histology coding rules are a hierarchy. They are listed in priority order and rule 1 has the highest priority. When determining the correct code to record for histology, begin with rule 1 and stop when you get to the first rule that applies. If rule 1 applies, there is no need to go any further. The rules for coding histology are found in the SEER Program Coding and Staging Manual 2004, pages 86-87. Additional information on coding histology for breast tumors is found in Appendix C, pages C471-472, of the SEER Program Coding and Staging Manual.The histology coding rules are a hierarchy.

15. Histology Coding Rules: Breast Single Tumor Code the histology if only one type is mentioned in the pathology report Example: Comedocarcinoma, UOQ right breast Answer: 8501/3 Comedocarcinoma The first set of rules is for single tumors. 1) Code the histology if only one type is mentioned in the pathology report. EXAMPLE: The patient has 1 lesion in the upper outer quadrant of the breast described as comedocarcinoma. The histology code is 8501/3, comedocarcinoma.The first set of rules is for single tumors. 1) Code the histology if only one type is mentioned in the pathology report. EXAMPLE: The patient has 1 lesion in the upper outer quadrant of the breast described as comedocarcinoma. The histology code is 8501/3, comedocarcinoma.

16. Histology Coding Rules: Breast Code the invasive histology when tumor is both invasive and in situ Example 1: Right breast tumor, tubular carcinoma with lobular carcinoma in situ Tubular carcinoma 8211/3 Lobular carcinoma in situ 8520/2 Answer: 8211/3 Tubular carcinoma 2) Code the invasive histology when tumor is both invasive and in situ. EXAMPLE 1: The single breast tumor contains both tubular carcinoma and lobular carcinoma in situ. The tubular carcinoma is recorded because it is invasive and the lobular carcinoma is in situ. The correct code is 8211/3.2) Code the invasive histology when tumor is both invasive and in situ. EXAMPLE 1: The single breast tumor contains both tubular carcinoma and lobular carcinoma in situ. The tubular carcinoma is recorded because it is invasive and the lobular carcinoma is in situ. The correct code is 8211/3.

17. Histology Coding Rules: Breast (Continued) Example 2: Ductal carcinoma in situ, 6 mm focus of invasive pure mucinous carcinoma, that appears to have arisen in intraductal papillary carcinoma of left breast Ductal carcinoma in situ 8500/2 Invasive mucinous carcinoma 8480/3 Intraductal papillary carcinoma 8503/2 Answer: 8480/3 Mucinous carcinoma EXAMPLE 2: This tumor includes ductal carcinoma in situ with a focus of invasive pure mucinous carcinoma that appears to have arisen in an intraductal papillary carcinoma. There are three histologic types in this tumor. Rule 2 instructs us to record the histology for the invasive portion of the tumor. The only portion of the tumor that is invasive is the mucinous carcinoma. The ductal and papillary are both in situ tumors. The histology that should be recorded is mucinous carcinoma, 8480/3, because it is invasive.EXAMPLE 2: This tumor includes ductal carcinoma in situ with a focus of invasive pure mucinous carcinoma that appears to have arisen in an intraductal papillary carcinoma. There are three histologic types in this tumor. Rule 2 instructs us to record the histology for the invasive portion of the tumor. The only portion of the tumor that is invasive is the mucinous carcinoma. The ductal and papillary are both in situ tumors. The histology that should be recorded is mucinous carcinoma, 8480/3, because it is invasive.

18. Histology Coding Rules: Breast (Continued) Exception: If the histology of the invasive component is an ‘NOS’ term (e.g., carcinoma, adenocarcinoma), then code the histology of the specific term associated with the in situ component and an invasive behavior Exception to rule 2: If the histology of the invasive component is an ‘NOS’ term (e.g., carcinoma, adenocarcinoma), then code the histology of the specific term associated with the in situ component and an invasive behavior. Exception to rule 2: If the histology of the invasive component is an ‘NOS’ term (e.g., carcinoma, adenocarcinoma), then code the histology of the specific term associated with the in situ component and an invasive behavior.

19. Histology Coding Rules: Breast (Continued) Example 3: Carcinoma and in situ ductal carcinoma, single lesion right UOQ breast Carcinoma, NOS 8010/3 In situ ductal carcinoma 8500/2 Answer: 8500/3 Infiltrating duct carcinoma EXAMPLE 3: The single breast lesion contains carcinoma, a malignant ‘NOS’ histology, and in situ ductal carcinoma, a specific histology with in situ behavior. The exception to rule 2 tells us to code the specific histology, in this case ductal carcinoma, and to code the malignant behavior from the ‘NOS’ histology. The correct code is 8500/3, infiltrating duct carcinoma.EXAMPLE 3: The single breast lesion contains carcinoma, a malignant ‘NOS’ histology, and in situ ductal carcinoma, a specific histology with in situ behavior. The exception to rule 2 tells us to code the specific histology, in this case ductal carcinoma, and to code the malignant behavior from the ‘NOS’ histology. The correct code is 8500/3, infiltrating duct carcinoma.

20. Histology Coding Rules: Breast Use a mixed histology code if one exists Use a combination code if one exists The next two rules pertain to mixed and combination codes. 3) Use a mixed histology code if one exists. 4) Use a combination code if one exists. Mixed or combination codes usually include the words “and” or “mixed” in the diagnosis. The next two rules pertain to mixed and combination codes. 3) Use a mixed histology code if one exists. 4) Use a combination code if one exists. Mixed or combination codes usually include the words “and” or “mixed” in the diagnosis.

21. Histology Coding Rules: Breast (Continued) Example 1: Invasive ductal carcinoma, mucinous type, and invasive lobular carcinoma; left breast single lesion Ductal carcinoma 8500/3 Lobular carcinoma 8520/3 Answer: 8522/3 Infiltrating duct and lobular carcinoma EXAMPLE 1: The histology is invasive ductal carcinoma and invasive lobular carcinoma. There is a combination code for infiltrating duct and lobular carcinoma, and it is 8522/3. The mucinous type is ignored because there is a combination code to use. Type indicates majority of tumor, but tumor majority is addressed in a later rule. The histology coding rules are a hierarchy. When you get to a rule that fits, you don’t go any further. So, use the combination code as stated in rule 4 and ignore the mucinous type. EXAMPLE 1: The histology is invasive ductal carcinoma and invasive lobular carcinoma.

22. Histology Coding Rules: Breast (Continued) Example 2: Left breast lesion, UOQ, duct carcinoma and tubular carcinoma Duct carcinoma 8500/3 Tubular carcinoma 8211/3 Answer: 8523/3 Infiltrating duct mixed with other types of carcinoma EXAMPLE 2: There is a single lesion with duct carcinoma and tubular carcinoma. The combination code for these histologies in one lesion is 8523/3, infiltrating duct mixed with other types of carcinoma. The alphabetic index of the ICD-O-3 Coding Manual directs you to this combination code. Infiltrating duct mixed with other types of carcinoma is the preferred term, but infiltrating duct and tubular carcinoma is an equivalent term and uses the same code.EXAMPLE 2: There is a single lesion with duct carcinoma and tubular carcinoma. The combination code for these histologies in one lesion is 8523/3, infiltrating duct mixed with other types of carcinoma. The alphabetic index of the ICD-O-3 Coding Manual directs you to this combination code. Infiltrating duct mixed with other types of carcinoma is the preferred term, but infiltrating duct and tubular carcinoma is an equivalent term and uses the same code.

23. Histology Coding Rules: Breast Code the more specific term when one of the terms is ‘NOS’ and the other is a more specific description of the same histology Example: Breast lesion, adenocarcinoma and mucinous adenocarcinoma Adenocarcinoma, NOS 8140/3 Mucinous adenocarcinoma 8480/3 Answer: 8480/3 Mucinous adenocarcinoma 5) Code the more specific term when one of the terms is ‘NOS’ and the other is a more specific description of the same histology. EXAMPLE: The single breast lesion contains adenocarcinoma and mucinous adenocarcinoma. Adenocarcinoma is an ‘NOS’ histology and mucinous adenocarcinoma is a more specific description of the same histology. Code the more specific description as instructed in rule 5. In this case mucinous adenocarcinoma is the histology to record because it is more specific. 5) Code the more specific term when one of the terms is ‘NOS’ and the other is a more specific description of the same histology. EXAMPLE: The single breast lesion contains adenocarcinoma and mucinous adenocarcinoma. Adenocarcinoma is an ‘NOS’ histology and mucinous adenocarcinoma is a more specific description of the same histology. Code the more specific description as instructed in rule 5. In this case mucinous adenocarcinoma is the histology to record because it is more specific.

24. Histology Coding Rules: Breast Code the majority of the tumor Terms that mean majority of tumor: Predominantly; with features of; major; type (eff. 1/1/99); with….differentiation (eff. 1/1/99); pattern and architecture (if in CAP protocol; eff. 1/1/2003) Terms documented in SEER PCSM 2004, page 85 6) Code the majority of the tumor. Terms that indicate tumor majority include predominantly, with features of, major, type (effective 1/1/99), with…differentiation (effective 1/1/99), and pattern and architecture (if in College of American Pathologists protocol, effective 1/1/2003). The list of majority terms is found on page 85 of the SEER Program Coding and Staging Manual 2004. 6) Code the majority of the tumor. Terms that indicate tumor majority include predominantly, with features of, major, type (effective 1/1/99), with…differentiation (effective 1/1/99), and pattern and architecture (if in College of American Pathologists protocol, effective 1/1/2003). The list of majority terms is found on page 85 of the SEER Program Coding and Staging Manual 2004.

25. Histology Coding Rules: Breast (Continued) Example 1: Breast tumor, duct adenocarcinoma with apocrine features Duct adenocarcinoma 8500/3 Apocrine adenocarcinoma 8401/3 Answer: 8401/3 Apocrine adenocarcinoma EXAMPLE 1: The breast tumor is described as duct adenocarcinoma with apocrine features. “Features” is a term that indicates majority of the tumor. Record the majority of the tumor as instructed in rule 6. The correct code is 8401/3, apocrine adenocarcinoma, because it is the majority of the tumor. If this tumor would have been described as duct adenocarcinoma and apocrine adenocarcinoma, the combination code, 8523/3 (infiltrating duct mixed with other types of carcinoma) would have been recorded. The use of the term “and” with the two histologies leads to a mixed or combination code.EXAMPLE 1: The breast tumor is described as duct adenocarcinoma with apocrine features. “Features” is a term that indicates majority of the tumor. Record the majority of the tumor as instructed in rule 6. The correct code is 8401/3, apocrine adenocarcinoma, because it is the majority of the tumor. If this tumor would have been described as duct adenocarcinoma and apocrine adenocarcinoma, the combination code, 8523/3 (infiltrating duct mixed with other types of carcinoma) would have been recorded. The use of the term “and” with the two histologies leads to a mixed or combination code.

26. Histology Coding Rules: Breast (continued) Terms that DO NOT mean majority of tumor With foci of; focus of/focal; areas of; elements of; component (eff.1/1/99) Terms documented in SEER PCSM 2004, page 85 Terms that do not mean majority of tumor are with foci of; focus of/focal; areas of; elements of; and component (effective 1/1/99). They are documented on page 85 of the SEER Program Coding and Staging Manual 2004. Terms that do not mean majority of tumor are with foci of; focus of/focal; areas of; elements of; and component (effective 1/1/99). They are documented on page 85 of the SEER Program Coding and Staging Manual 2004.

27. Histology Coding Rules: Breast (Continued) Example 2: Right breast LIQ, lobular carcinoma in situ with areas of cribriform carcinoma in situ Lobular carcinoma in situ 8520/2 Cribriform carcinoma in situ 8201/2 Answer: 8520/2 Lobular carcinoma in situ EXAMPLE 2: The single breast tumor is described as lobular carcinoma in situ with areas of cribriform carcinoma in situ. “With areas of” does not indicate majority of tumor. The lobular carcinoma in situ is considered the majority and would be recorded for histology. The correct code is 8520/2.EXAMPLE 2: The single breast tumor is described as lobular carcinoma in situ with areas of cribriform carcinoma in situ. “With areas of” does not indicate majority of tumor. The lobular carcinoma in situ is considered the majority and would be recorded for histology. The correct code is 8520/2.

28. Histology Coding Rules: Breast Code the numerically higher ICD-O-3 code Example: Left breast, apocrine and mucinous adenocarcinoma Apocrine adenocarcinoma 8401/3 Mucinous adenocarcinoma 8480/3 Answer: 8480/3 Mucinous adenocarcinoma 7) Code the numerically higher ICD-O-3 code. This is the last rule for single tumors. This rule should be used infrequently. EXAMPLE: The single left breast tumor contains apocrine and mucinous adenocarcinoma. None of the previous rules applies so the histology recorded is that with the higher ICD-O-3 code. In this case the higher code is 8480/3, mucinous adenocarcinoma.7) Code the numerically higher ICD-O-3 code. This is the last rule for single tumors. This rule should be used infrequently. EXAMPLE: The single left breast tumor contains apocrine and mucinous adenocarcinoma. None of the previous rules applies so the histology recorded is that with the higher ICD-O-3 code. In this case the higher code is 8480/3, mucinous adenocarcinoma.

29. Histology Coding Rules: Breast Multiple Tumors with Different Behaviors in Same Organ Reported as Single Primary Code the histology of the invasive tumor when one lesion is in situ and the other is invasive Example: 2 lesions, right breast: 1) LOQ, invasive lobular CA 8520/3 2) UIQ, noninfiltrating lobular CA 8520/2 Answer: 8520/3 Lobular carcinoma, NOS This rule is used when there are multiple tumors with different behaviors in the same organ reported as a single primary. Code the histology of the invasive tumor when one lesion is in situ and the other is invasive. EXAMPLE: There are 2 lesions in the right breast. The lesion in the lower outer quadrant contains invasive lobular carcinoma, histology with malignant behavior, and the lesion in the upper inner quadrant contains noninfiltrating lobular carcinoma, the same histology with in situ behavior. This is one primary, and the malignant histology, 8520/3 lobular carcinoma, is recorded.This rule is used when there are multiple tumors with different behaviors in the same organ reported as a single primary.

Histology Coding Rules: Breast Code the more specific term when one of the terms is ‘NOS’ and the other is a more specific description of the same histology Example: Right breast 1) UIQ, carcinoma 8010/3 2) LIQ, cribriform carcinoma 8201/3 Answer: 8201/3 Cribriform carcinoma 5) Code the more specific term when one of the terms is ‘NOS’ and the other is a more specific description of the same histology. EXAMPLE: The patient has two lesions in the right breast. The lesion in the upper inner quadrant is carcinoma, an ‘NOS’ histology. The lesion in the lower inner quadrant is cribriform carcinoma, a more specific description of carcinoma. The more specific histology, cribriform carcinoma, 8201/3, is recorded.5) Code the more specific term when one of the terms is ‘NOS’ and the other is a more specific description of the same histology.

34. Histology Coding Rules: Breast Code all other multiple tumors with different histologies as multiple primaries Example: Left breast 1) UOQ, lobular carcinoma 8520/3 2) LIQ, mucinous carcinoma 8480/3 Answer: 2 primary sites; complete abstract for each one 6) Code all other multiple tumors with different histologies as multiple primaries. If there are two lesions in the same breast, they are considered two primaries if the histology in each lesion is different. If none of the previous five rules applies to the situation, the histology is different and the two lesions are considered separate primaries. EXAMPLE: There are two lesions in the left breast. The upper outer quadrant lesion is lobular carcinoma, and the lower inner quadrant lesion is mucinous carcinoma. None of the previous five rules applies, and the histologies are different. The two lesions of the left breast are considered separate primaries and two abstracts are completed. 6) Code all other multiple tumors with different histologies as multiple primaries.

35. Coding Behavior for Breast Confined to epithelium Intracystic Intraductal Intraepidermal Intraepithelial No stromal invasion Noninfiltrating Noninvasive Stage 0 We have completed the discussion of histology coding rules and will now discuss coding behavior for breast cancer. In situ breast tumors, behavior code 2, and malignant breast tumors, behavior code 3, are reportable. Synonyms for in situ for breast cancer include confined to epithelium, intracystic, intraductal, intraepidermal, intraepithelial, no stromal invasion, noninfiltrating, noninvasive, and stage 0. When these descriptions are used and there is no documentation of any invasive disease, the ICD-O-3 behavior code is 2.

36. Coding Grade for Breast Histologic grade, differentiation, codes 1 = well differentiated 2 = moderately differentiated 3= poorly differentiated 4= undifferentiated Grade is the measurement of how closely cancer cells resemble the cells of the organ in which the cancer originated. Code 1 indicates that the cancer cells closely resemble those of the organ of origin. As the grade number increases, the resemblance of cancer cells to those of the organ of origin decreases. Grade 4 cancers have little or no resemblance to the cells of the organ of origin. The general code definitions for grade are shown on this slide; 1 is well differentiated, 2 is moderately differentiated, 3 is poorly differentiated, and 4 is undifferentiated.

37. Coding Grade for Breast Bloom-Richardson (BR) Score Frequency of cell mitosis Tubule formation Nuclear pleomorphism Bloom-Richardson Grade Low grade = BR score 3-5 = grade 1 Intermediate grade = BR score 6, 7 = grade 2 High grade = BR score 8, 9 = grade 3 Bloom-Richardson (BR) is the grading system used most often for breast cancer. A score between 1 and 3 is assigned to three categories. The sum of the three scores is the BR score. The range for BR scores is between 3 and 9. The score for the first category is based on the frequency of cell mitosis or cell division. The second category is tubule formation, and the score is based on the percentage of cancer composed of tubular structures. The third category is nuclear pleomorphism, and the score is based on the change in cell size and uniformity. BR may also be called modified Bloom-Richardson, Scarff-Bloom-Richardson, SBR grading, BR grading, Elston-Ellis modification of Bloom Richardson score, the Nottingham modification of Bloom Richardson score, Nottingham-Tenovus, or Nottingham grade. BR may also be expressed as a grade. BR score of 3-5 is low grade and is recorded as grade 1; BR score of 6 or 7 is intermediate grade and is recorded as grade 2; and BR score of 8 or 9 is high grade and is recorded as grade 3.Bloom-Richardson (BR) is the grading system used most often for breast cancer.

Coding Grade for Breast Code grade for breast cancer in the following priority order per FORDS, page 13, and SEER PCSM 2004, page 94: Bloom-Richardson scores converted to grade Bloom-Richardson grade Nuclear grade Terminology Histologic grade Some pathology reports include multiple grading systems for the same breast cancer. If different grading systems are used to describe the same cancer, code grade in the following priority order: 1) Bloom-Richardson scores; 2) Bloom-Richardson grade; 3) nuclear grade; 4) terminology; and 5) histologic grade. This is documented in FORDS, page 13, and in SEER Program Coding and Staging Manual 2004, page 94. Some pathology reports include multiple grading systems for the same breast cancer.

39. Breast Grading Conversion Table The table shown on this slide is a conversion table for breast grade. It is used to convert the documented grade to the appropriate code. The first five columns list the description for a specific grading system used for breast cancer, and the last column lists the code that matches the description. The columns are in priority of use order as described on the previous slide. So, if the BR score is 4, the grade code is 1. If there is no BR score or grade but nuclear grade is documented as 2/3, then the code is 2. If the only description of grade is poorly differentiated, the grade code is 3. If the BR score is documented as 7 and the tumor is also described as poorly differentiated, code 2 is assigned because the BR score takes priority over terminology.

44. Breast Cancer Work-up Physical examination Breast exam Evaluation of lymph nodes Imaging studies Mammography Breast ultrasound Bone scan Chest x-ray Work-up for breast cancer begins with the physical examination. The breast should be examined and palpated for a mass. Lymph nodes should be evaluated for swelling or adenopathy. Mammography is used to identify location and other characteristics of a palpable breast mass. It is also used as a screening tool to identify possible breast malignancies before a mass is palpable. Breast ultrasound may also be used to identify characteristics of a breast mass including size and location. Bone scan and chest x-ray both help in identification of metastasis.

47. Laterality for Breast Code the laterality for the breast in which the tumor originated Count cancer in both breasts as separate primaries unless metastasis from one side to the other is documented Code laterality for all breast subsites Laterality describes the side of a paired organ or side of the body on which a tumor originates. The breasts are paired organs. If both sides of a paired organ contain cancer, they are counted as separate primaries unless one side is described as metastatic from the other. Laterality must be coded for all breast subsites. Laterality describes the side of a paired organ or side of the body on which a tumor originates. The breasts are paired organs.

CS Extension Breast: Notes Inflammatory carcinoma Clinical AND pathologic entity Characterized by presence of diffuse erythema and edema (peau d'orange) of breast Often occurs without an underlying palpable mass Clinical findings should involve the majority of the skin of the breast 5) Inflammatory carcinoma of the breast is a clinical entity as well as a pathologic diagnosis. Clinically it presents with diffuse erythema and edema of the breast and it does not always include an underlying palpable breast mass. The clinical findings such as erythema and edema should involve the majority of the skin of the breast for a diagnosis of inflammatory carcinoma.5) Inflammatory carcinoma of the breast is a clinical entity as well as a pathologic diagnosis.

54. CS Extension Breast: Notes Inflammatory carcinoma (cont.) Skin changes arise quickly in the affected breast Neglected locally advanced breast cancer is not inflammatory carcinoma Mass and thickening of the skin over the breast may be detectable on imaging Due to tumor emboli within dermal lymphatics that may or may not be apparent on skin biopsy Skin changes usually arise quickly in the breast affected by inflammatory carcinoma. Inflammatory carcinoma should not be used as a diagnosis for those patients who present with a neglected locally advanced cancer. The presentation is similar but it is not inflammatory carcinoma. On imaging of a breast with inflammatory carcinoma, a detectable mass and thickening of the skin over the breast may be identified due to tumor emboli within the dermal lymphatics. The tumor emboli may or may not be apparent on skin biopsy. Skin changes usually arise quickly in the breast affected by inflammatory carcinoma.

55. CS Extension Breast: Notes Inflammatory carcinoma (continued) Pathologic involvement of the dermal lymphatics alone does not indicate inflammatory carcinoma Biopsy is needed to demonstrate dermal lymphatic or breast parenchyma involvement Because inflammatory carcinoma is primarily a clinical diagnosis, involvement of dermal lymphatics alone without clinical findings is not a diagnosis of inflammatory carcinoma. Along with clinical findings, however, a biopsy is necessary to demonstrate involvement of dermal lymphatics or breast parenchyma.

70. CS Extension Breast Inflammatory carcinoma This diagram illustrates inflammatory carcinoma of the breast. As discussed previously, inflammatory carcinoma is both a clinical and pathologic entity. To assign the CS extension codes for inflammatory carcinoma, 71 and 73, there must be both clinical and pathologic evidence of the condition. Inflammatory carcinoma of the breast is an advanced and accelerated breast cancer that requires immediate aggressive treatment. This usually is chemotherapy followed by surgery. Inflammatory carcinoma has a higher risk of recurrence than other forms of breast cancer.This diagram illustrates inflammatory carcinoma of the breast.

72. CS Lymph Nodes Breast: Notes Code only regional nodes and nodes, NOS; distant nodes are coded in CS Mets at DX If nodes are positive but size of the metastasis is not stated, assume the metastasis is > 0.2 mm and code the lymph nodes as positive in this field; if no specific information, use code 60 These are the coding notes that proceed the CS lymph nodes codes in the CS Manual. 1) Only regional lymph node involvement is coded in CS lymph nodes. Involvement of distant lymph nodes is coded in CS mets at dx. 2) If the nodes are positive but the size of involvement is not stated, assume the size of metastasis is greater than 0.2 mm and code as lymph node involvement. The difference in definition between lymph node involvement and isolated tumor cells is based on the size of the involvement and the biologic activity. Metastasis in the lymph region of the breast greater than 0.2 mm in size is defined as lymph node involvement. When there is lymph node involvement but the specific lymph node region is not documented, assign CS lymph nodes code 60. The definition for code 60 is axillary/regional lymph nodes, NOS or lymph nodes, NOS. These are the coding notes that proceed the CS lymph nodes codes in the CS Manual. 1) Only regional lymph node involvement is coded in CS lymph nodes. Involvement of distant lymph nodes is coded in CS mets at dx. 2) If the nodes are positive but the size of involvement is not stated, assume the size of metastasis is greater than 0.2 mm and code as lymph node involvement.

CS Lymph Nodes Breast: Notes If no lymph nodes were surgically removed, use only these codes for clinical evaluation of axillary nodes: 00 - Clinically negative 50 - Fixed/matted nodes 60 - Clinically positive axillary nodes 99 - Unknown/not stated 3) If lymph nodes were not surgically removed, use clinical information to code CS lymph nodes. The codes that are applicable to describe the clinical evaluation of the axillary nodes are: 00, clinically negative; 50, fixed/matted nodes; 60, clinically positive axillary nodes; and 99, unknown/not stated. The other codes for CS lymph nodes are not applicable in this situation. 3) If lymph nodes were not surgically removed, use clinical information to code CS lymph nodes.

74. CS Lymph Nodes Breast: Notes If pre-surgical therapy is given and there is clinical evaluation of nodes, use only the following for clinical evaluation of axillary nodes AND code a '5' in “CS Reg Nodes Eval” field: 00 - Clinically negative 50 - Fixed/matted nodes 60 - Clinically positive axillary nodes If there is no clinical evaluation of nodes, use information from path evaluation and code a '6' in “CS Reg Nodes Eval” field 4) If the patient receives adjuvant therapy such as radiation or chemotherapy prior to surgical removal of lymph nodes, the clinical evaluation of the regional nodes should be used to code CS lymph nodes. The applicable codes in this situation are: 00, clinically negative; 50, fixed/matted nodes; and 60, clinically positive axillary nodes. We are not discussing the use of evaluation codes in this presentation, but it is important to note that in this situation evaluation code 5 is used to indicate the lymph node status was based on clinical information. In the case where there is no clinical evaluation of lymph nodes in a patient that received adjuvant therapy prior to surgical removal of lymph nodes, code the lymph node involvement information from the pathology report and assign code 6 in the evaluation field. Evaluation code 6 indicates that the lymph node status was coded from pathology information gathered after the patient had pre-surgical adjuvant therapy. 4) If the patient receives adjuvant therapy such as radiation or chemotherapy prior to surgical removal of lymph nodes, the clinical evaluation of the regional nodes should be used to code CS lymph nodes.

112. Scope of Regional Lymph Node Surgery: Breast Code sentinel lymph node biopsy Biopsy of first axillary node to receive lymph drainage from breast If sentinel node is negative, axillary dissection may not be needed Code axillary lymph node dissection Patients with breast cancer may receive a sentinel lymph node biopsy as part of work-up and treatment. The sentinel lymph node biopsy evaluates the first axillary node to receive lymph drainage from the breast. If that node is negative, the patient may not have lymph node metastasis and an axillary lymph node dissection may not be needed. Patients who have breast conserving surgery may also have a lymph node dissection. That procedure is coded in scope of regional lymph node surgery. Removal of the axilla is part of a modified radical, radical, or extended radical mastectomy. If lymph nodes are found in the axilla that is removed, the dissection of the nodes is recorded in scope of regional lymph node surgery.

Surgical Procedure/Other Site: Breast Record removal of distant lymph nodes or other tissues beyond the primary site Resection of cervical lymph nodes Removal of contralateral breast with metastatic disease Do not record surgical removal of ovaries in surgical procedure/other site If distant lymph nodes or tissues beyond the primary site are removed, the procedure is coded in the data item, surgical procedure/other site. The resection of a cervical lymph node as part of breast cancer treatment would be coded in surgical procedure/other site because cervical lymph node is distant for breast. If a patient has the contralateral breast removed and it is diagnosed with metastatic cancer, the procedure is coded in this data item. However, if the contralateral breast is determined to be a second primary, do not code the procedure in the data item, surgical procedure/other site. A second abstract is completed, and the surgery is coded in surgical procedure of primary site for the second primary. If part of first course surgery includes bilateral surgical removal of the ovaries, do not code as surgical procedure/other site. Ovarian ablation is coded in the data item, hematologic transplant and endocrine procedures.

It may be given as adjuvant therapy with breast conserving surgery or given pre-operatively when a patient has lymph node metastasis at the time of diagnosis. Some of the agents include but are not limited to anthracyline, adriamycin, methatrexate, and herceptin. If only one chemotherapy agent is given, it is coded as a single agent; but if multiple chemotherapeutic drugs are given in combination, they are coded as multiple agents. Multiple agent regimens for breast cancer include CMF (cyclophosphamide, methotrexate, 5-FU) and CAF (cyclophosphamide, adriamycin, 5-FU). When a regimen is given, check the drugs on the SEER Rx database to determine what type of drug is included in the regimen. If multiple drugs are chemotherapeutic, code as multiple agent chemotherapy. If hormone therapy is part of the regimen, code it in the data item for hormone therapy.
